Abstract: An economical and reliable system for the contained transfer of particulates by means of a series of transfer containers facilitates the particulate transfer without either exposure of the operating personnel and the environment to the particulate, or environmental contamination of the particulate itself. The system employs a multiple o-ring canister assembly which can be attached to either the discharging port or charging port of a piece of processing equipment. The canister has a series of circumferential o-ring grooves which allows the attachment of a series of individual transfer containers. In a charging mode, once the particulate is charged to the processing equipment, a first transfer container is collapsed and a second transfer container is placed in the next o-ring groove, thereby containing the remaining contaminated section of the first transfer container. The first transfer container is removed through a bag-out sleeve which is an integral part of the second transfer container.

Abstract: An inflatable structure, such as a fabric confining a gas, can be regulated as to its shape by the provision of auxiliary tubes, integral or adjacent to the fabric which can be separately pressurized. The separate pressurization will create local tensile forces to change the shape of the structure. Alternatively, a mechanical system, such as tensioned cables can be used to control the shape of the structure.
